Kate Hudson "comes clean" about her divorce from rocker-hubby Chris Robinson, Us magazine promises. Turns out the confessional is less than illuminating.

The magazine got an excerpt from Vogue's January cover story in which Hudson posed with son Ryder, 3, in matching fedoras and plaid-on-plaid ensembles that in any other venue would get them the beating of their lives (and deservedly so). Anyway, here's the big payoff: "We had Ryder, and we both sort of looked at each other and went, 'Something's off.'"

One question: Did anyone think to check the diaper?

(Did we really expect any major revelations? After all, it was Vogue that declared in a July 2006 interview with Hudson that "Mrs. Robinson has her family and career right on track." She and Robinson announced their split the following month.)

The divorce was "the most difficult thing I've ever done in my life," Hudson continues in the new profile. "The process of discovering with somebody that you love that you don't work is so painful."

More painful, even, than discussing your ex-boyfriend's much-publicized suicide attempt in a fashion glossy. Of ex Owen Wilson she says: "Owen is such a lovely person, and I love him dearly. And I wish him beautiful things -- health and everything that he desires in life."
